Summary

Anterior cruciate ligament (ACL) tears are among the most frequent traumatic knee injuries that occur in physically active individuals. Despite advances in minimally invasive surgical reconstruction techniques and aggressive rehabilitation, this atrophy and loss of strength can persist even after patients return to full activity and can place them at considerable risk for re-injury and developing osteoarthritis (OA). The design of new therapeutic interventions to prevent muscle atrophy is needed to advance the care of patients who suffer from ACL injuries. The growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis plays an important role in promoting muscle growth and protecting muscle from atrophy. While GH therapy has shown promise in protecting immobilized muscle from various models of disuse atrophy, it remains unknown whether GH can help to restore strength and protect against the loss in strength that occurs after ACL tear. GH therapy may help to accelerate the safe return to play of patients that suffer ACL tears, and help to prevent the long-term OA and reduction in quality of life that occur after these traumatic knee injuries.

Conditions

  • Rupture of Anterior Cruciate Ligament

Interventions

DRUG

Somatropin

GH dose will be calculated by nomogram estimation of body surface area, and will be administered via subcutaneous injection in the abdominal area twice per day (BID) at a dose of 0.5mg GH per body surface area (BSA) in m2 (0.5mg/m2). Patients will begin GH treatment one week prior to surgery and will continue through 5 weeks after surgery. On the day of surgery, patients will not take GH, but otherwise patients will take GH every day over this 6 week period.

DRUG

Placebo

A placebo diluent that will be administered via subcutaneous injection in the abdominal area twice per day (BID) at a dose of the equivalent concentration of 0.5mg GH per body surface area (BSA) in m2 (0.5mg/m2). Patients will begin treatment one week prior to surgery and will continue through 5 weeks after surgery. On the day of surgery, patients will not take medication, but otherwise patients will take medication every day over this 6 week period.
